0e870980a6 8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx
The number of CPUs are getting detected dynamically by checking the
processor SVR value.  Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.

This can help to use the same u-boot image across the platforms.

Also revamped and corrected few Freescale Copyright messages.

ad19e7a5d2 pci/fsl_pci_init: Rework PCI ATMU setup to handle >4G of memory
The old PCI ATMU setup code would just mimic the PCI regions into the
ATMU registers.  For simple memory maps in which all memory, MMIO, etc
space fit into 4G this works ok.  However there are issues with we have
>4G of memory as we know can't access all of memory and we need to
ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with
anything since we can't turn it off.

We first setup outbound windows based on what the board code setup
in the pci regions for MMIO and IO access.  Next we place PCICSRBAR
below the MMIO window.  After which we try to setup the inbound windows
to map as much of memory as possible.

On PCIe based controllers we are able to overmap the ATMU setup since
RX & TX links are separate but report the proper amount of inbound
address space to the region tracking to ensure there is no overlap.

On PCI based controllers we use as many inbound windows as available to
map as much of the memory as possible.

Additionally we changed all the CCSR register access to use proper IO
accessor functions.  Also had to add CONFIG_SYS_CCSRBAR_PHYS to some
86xx platforms that didn't have it defined.

7649a590b5 86xx: Cleanup MP support
* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx
* Introduce determine_mp_bootpg() helper.  We'll need this to address a
  bug introduced in v2009.03 with 86xx MP booting.  We have to make sure
  to reserve the region of memory used for the MP bootpg() so other
  u-boot code doesn't use it.
* Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to
  allow cmd_mp.c to build and work. In the future we should look at
  implementing all these functions. This could be common w/85xx if we
  use spin tables on 86xx.

79e436cad3 sbc8641d: Fix PCI mapping concepts
Rename _BASE to _BUS, as it's actually a PCI bus address,
separate virtual and physical addresses into _VIRT and _PHYS,
and use each appopriately.  This makes the code easier to read
and understand, and facilitates mapping changes going forward.

bf9a8c3430 mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLY
We define CONFIG_MONITOR_BASE_EARLY to define the initial location
of the bootpage in flash.   Use this to create an early mapping
definition for the FLASH, and change the early_bats code to use this.

This  change facilitates the relocation of the flash since the early
mappings are no longer tied to the final location of the flash.

c2083e0e11 86xx: Convert all fsl_pci_init users to new APIs
Converted MPC8610HCPD, MPC8641HPCN, and SBC8641D to use
fsl_pci_setup_inbound_windows() and ft_fsl_pci_setup().

With these changes the board code is a bit smaller and we get dma-ranges
set in the device tree for these boards.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

13f5433f70 86xx: Convert sbc8641d to use libfdt.
This is the proper fix for a missing closing brace in the function
ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com.
The ft_cpu_setup() function in mpc8641hpcn.c should have been
removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE,
but was missed.  Only, the sbc8641d was nominally still using it.
It all got ripped out, and the funcality that was in ft_board_setup()
was refactored to remove the CPU portions into the new file
cpu/mpc86xx/fdt.c instead.  Make sbc8641d use this now.

Based loosely on an original patch from joe.hamman@embeddedspecialties.com

to update TSEC1's device-tree node, so we need to add it

since they will eventually do something similar.

3a79013e2a Define tsec flag values in config files
The tsec_info structure and array has a "flags" field for each
ethernet controller.  This field is the only reason there are
settings.  Switch to defining TSECn_FLAGS for each controller
in the config header, and we can greatly simplify the array, and
also simplify the addition of future boards.
